Force of a tennis serve. For a top player, a tennis ball may
leave the racket on the serve with a speed of 55 m/s (about 120
mi/h). If the ball has a mass of 0.060 kg and is in contact with
the racket for about 4 ms (4 × 10- 3 s), estimate the average force
on the ball. Would this force be large enough to lift a 60- kg
person? Do we need to consider the weight of the ball in this
estimation? Why?
